Art dealer Andrew Crispo – once implicated in the sadomasochistic murder of a fashion student – was charged yesterday with threatening to kidnap a 4-year-old child in a bankruptcy dispute.

Crispo, 53, was charged with obstructing justice in Manhattan federal court for allegedly making the threats after he didn’t get money he demanded from his bankruptcy trustee.

The girl is the daughter of a female lawyer who formerly worked for the trustee, who is overseeing Crispo’s assets during Chapter 11 proceedings.

Neither the trustee nor the lawyer was identified.

The complaint said that on May 17, Crispo grew angry when a paralegal told him the trustee had not signed checks he had requested.

He told the aide the lawyer who had handled his bankruptcy “screwed” him out of money, the complaint charged.

Crispo then told the aide he had photographs of the lawyer’s daughter at a Central Park playground and would kidnap her, the complaint charged.

Crispo was carrying crack cocaine and two glass pipes when he was arrested Monday night, Assistant U.S. Attorney David Greenwald said at Crispo’s arraignment yesterday. He was ordered held without bail.

“Mr. Crispo disputes the allegations,” said his lawyer, Wayne Greenwald.

In 1985, Crispo was implicated in the sadomasochistic murder of fashion student Eigel Vesti.

Bernard LeGeros, an employee of Crispo’s, said Crispo ordered the murder after a sex-and-torture session.
